【摘要】：目的:比较个性化舌侧矫治与唇侧直丝弓矫治患者牙齿和骨骼关系的X线头影测量结果,为指导正畸临床选择矫治系统提供可靠的理论依据。方法:根据患者全身情况、错牙合畸形分类、牙列拥挤程度和矫治设计确定入选标准,选择临床上常见的成人错牙合畸形病例共30例。将所选患者随机分为个性化舌侧矫治组和唇侧直丝弓矫治组,每组15例。采用Steiner及Tweed头影测量分析方法进行X线头影测量,对2组患者治疗前及治疗后的头影测量数据进行对比分析,并对比2组患者的矫治疗程,评价2种不同矫治系统的治疗效果和疗程。结果:矫治结束后,2组患者磨牙及尖牙关系均为中性关系,前牙呈浅覆牙合浅覆盖,牙齿排列整齐,尖窝相对并且无余留间隙。Steiner头影测量分析,2组患者各项头影测量值比较差异均无统计学意义(P0.05);Tweed头影测量分析,2组患者各项头影测量值比较差异均无统计学意义(P0.05);2种分析法患者治疗前后差值比较差异亦均无统计学意义(P0.05);2组患者临床矫治疗程比较差异无统计学意义(P0.05)。结论:无论采用个性化舌侧矫治还是唇侧直丝弓矫治均可获得良好的牙齿排列及牙合关系,达到令人满意的临床矫治效果。
[Abstract]:Objective: to compare the results of X-ray cephalometric measurements of the relationship between the tooth and bone in patients with individualized lingual correction and labial straight wire appliance, so as to provide a reliable theoretical basis for guiding the clinical selection of orthodontic orthodontics. Methods: according to the patients' general condition, malocclusion classification, dentition crowding degree and orthodontic design, 30 cases of adult malocclusion were selected. The patients were randomly divided into two groups: the lingual side correction group and the labial straight wire appliance group with 15 cases in each group. Steiner and Tweed cephalometric analysis were used to measure the cephalometric data before and after treatment in two groups. To evaluate the therapeutic effect and course of treatment of two different orthodontic systems. Results: the relationship between molars and canines was neutral, the anterior teeth were covered with shallow overbite, and the teeth were arranged neatly. Comparison of cephalometric values of two groups of patients without residual space there was no significant difference in cephalometric values between the two groups; there was no significant difference in the cephalometric values of the two groups of patients with Tweed cephalometric analysis; there was no significant difference in the cephalometric values of two groups of patients with no significant difference in the cephalometric values of the two groups. There was no significant difference between the two groups before and after treatment. There was no significant difference in the course of treatment between the two groups (P 0.05). Conclusion: good tooth arrangement and occlusal relationship can be obtained either by individualized tongue side correction or lip straight wire appliance, and satisfactory clinical effect can be achieved.
